Scissors-style doors were just one of the unconventional features of the Neon Aviat concept, billed as a sport coupe for the 21st century. The Aviat had bodywork that wrapped inside the rear wheels. Note the huge air scoop ahead of the rear wheel, and the full fender skirt.
Based on the Dodge/Plymouth Neon, the Aviat concept was a computer generated creation for a 21st century sports coupe with excellent coefficient of drag. Power was supplied by a DOHC 16-valve 2.0-liter inline 4-cylinder that produced 145 horses, and although the engine was front-mounted, the cooling system was repositioned within the outrigger-style rear-quarter fenders.
